OR, odds ratio; 95% CI, 95% confidence interval.

^#Adjusted for significant variables include age, sex, BMI, comorbidity (hypertension, chronic heart failure, and chronic kidney disease), blood gas results (pH value, base excess, anion gap, bicarbonate, and lactate), laboratory tests (white blood cell count, platelets count, hemoglobin, serum creatinine, and international normalized ratio), SOFA score, and SIRS score.
